Peer ( English peer ) - an equal participant (user) of the network, providing services to other participants of the peer-to-peer network and using their services himself. Often this is the name of the client participating in the distribution in file-sharing networks . It is the opposite of the client or server in the client-server architecture, because the services they provide and use.

At BitTorrent
There are two types of feasts in BitTorrent networks: siders (or seeders) - those who have the file / package completely and only distributes it, and leechers (or lychees) - those who still have the incomplete file / package and download it from the siders and + distributes leechers to other leechers.
Sid
( eng . seeder - seeder, abbreviated as seed ) - exchange participant (feast), having all segments (blocks, fragments) of the distributed distribution.
Leach (Leach)
( English leech - leech) - a feast that does not yet have all segments, that is, continues to download, or has already finished downloading the selected parts of the distribution.
The term is sometimes used in the negative sense that it has in other file-sharing networks: a user who gives away much less than he downloads. However, (for example, in the terminology of the BitTorrent network), the term “leecher” can mean any user who downloads a file for himself, or has already downloaded a part from the distributed material or file and does not carry a negative meaning .
In the terminology of µTorrent, “Sides” are peers identified by the client, just like seeds. The client contacted them and knows that these are complete sources. “Feasts,” according to µTorrent terminology, are all remaining participants in the swarm. Among them can be identified as client-identified lychees (they are indicated in brackets), and generally not identified members of the swarm, which can be both sids and persons. That is why the generic name "Peers" is used. Identifying them with personalities is a gross mistake. Saying that µTorrent uses a different terminology is also incorrect.
General arithmetic for the “Peers” column in µTorrent:
The number in front of the brackets is the total number of feasts with the exception of identified seeds;
The number in parentheses is the identified lychee;
The difference between the numbers before the brackets and in the brackets is not identified feasts, which can be either sids or personalities.
